Abstract

A study was conducted to investigate the effects of EDTA. and Chelex-lOO on the glutamate
dehydrogenase activity from a crude extract of the developing seeds of Lupinus angustifolius. The enzyme
was not inhibited by Chelex-lOO; instead it was highly stimulated and its activity, when treated with
Chelex-lOO, was higher than that of the control. Glutamate dehydrogenase, however, was inhibited by
5mM EDTA, stimulated at 30mM EDTA, and inhibited again at 45mM EDTA.
